Does the choice of observation instrument make a difference in the feedback and ratings that teachers receive? This study explores how lessons are rated differentially across various observation instruments. To investigate this question, ten randomly selected mathematics lessons were rated using six different observation instruments. Overall…

An essential feature of many modern teacher observation protocols is their "global" approach to measuring instruction. Global protocols provide a summary evaluation of multiple domains of instruction from observers' overall review of classroom processes. Although these protocols have demonstrated strengths, including their…

Using students' assessments of teaching at a top university in China from 2016 to 2021, this study examines whether evaluation of teaching improves teaching quality. Given the many doubts about the validity of students' evaluation of teaching, this study adopts a methodology to distinguish teaching quality improvement from the reversal effect. It…

Teacher evaluations can be used by states and districts to support and develop an exceptional workforce. Accurate evaluations based on quality data can help differentiate teacher performance, inform feedback, improve professional development, provide opportunities for pay increases and advancement, and provide rationale for teacher dismissals. Yet…

The purpose of this qualitative case study was to describe/summarize the perceptions of the North Carolina Educator Evaluation System (NCEES) for 10 educational leaders in two small rural school districts in eastern North Carolina. This study was conducted through the problem definition lens. The 10 educational leaders for this study included two…

Student ratings are not leaving today or anytime soon. However, as the title of this article indicates, student ratings are not the only option to provide evidence in the evaluation of teaching. There is a broad range of alternatives to consider beyond student ratings in the delicate decision-making processes to improve teaching and determine the…

While it is generally assumed that the aim of teacher evaluation is to "formatively" support teachers' professional development, research finds that teacher evaluation practices are predominantly "summative". This paper describes a Norwegian governmental policy experiment aiming to overcome this fallacy through a bargaining…

Teacher effectiveness varies substantially, yet principals' evaluations of teachers often fail to differentiate performance among teachers. We offer new evidence on principals' subjective evaluations of their teachers' effectiveness using two sources of data from a large, urban district: principals' high-stakes personnel evaluations of teachers,…

The purpose of this statement is to inform those using or considering the use of value-added models (VAM) about their scientific and technical limitations in the evaluation of educators and programs that prepare teachers. The statement briefly reviews the background and current context of using VAM for evaluations, enumerates specific psychometric…

The five thoughtful papers included in this issue of "Educational Researcher" ("ER") raise new questions about the use of value-added methods (VAMs) to estimate teachers' contributions to students' learning as part of personnel evaluation. The papers address both technical and implementation concerns, considering potential…

The Scylla and Charybdis in this discussion of teacher evaluation are standardized achievement test data on the one hand, and classroom observational systems on the other. These are the two most common methods used to judge teachers' competency. Both have serious flaws: the former primarily with validity, the latter primarily with reliability. At…

Background: There has been rapid growth in value-added assessment of teachers to meet the widely supported policy goal of identifying the most effective and the most ineffective teachers in a school system. The former group is to be rewarded while the latter group is to be helped or fired for their poor performance. But, value-added approaches to…

Australian universities are increasingly resorting to the use of journal metrics such as impact factors and ranking lists in appraisal and promotion processes, and are starting to set quantitative "performance expectations" which make use of such journal-based metrics. The widespread use and misuse of research metrics is leading to…

Quantitative measures of student performance are increasingly used as proxies of educational quality and teacher ability. Such assessments assume that the quality of educational practices can be unambiguously quantitatively measured and that such measures are sufficiently precise and robust to be aggregated into policy-relevant rankings like…
